Why use Scan to PDF?
Automatic detection
OpenCV.js finds the four corners in the photo — even when shot at an angle.
Perspective correction
Skew is corrected automatically so the page looks straight and framed.
Black & white filter
Adaptive thresholding for crisp text on a clean white background.
Multi-page
Add several photos to build a multi-page PDF in one go.
Frequently asked questions
- How do I scan a document without a scanner?
- Take a photo with your phone and import it. The tool detects edges, fixes perspective and outputs a clean PDF — no hardware required.
- How do I turn a photo into a clean PDF?
- Import the photo, adjust the crop if needed, pick the “Black & white” filter for best results, then click “Generate PDF”.
- Does it work on iPhone and Android?
- Yes — it is mobile-first. “Take a photo” opens the camera. Native Web Share works on iOS and Android too.
- How do I scan several pages into one PDF?
- After the first page, click “+ Add page” at step 4. Each photo becomes another page; drag and drop to reorder.
- How is this different from a real scanner?
- A physical scanner uses even lighting. This tool compensates with perspective correction and an adaptive filter. For everyday documents, results are comparable.
